chassis between the disk drives and the I/O board assembly. There are also three external
hot-swappable fans located at the rear of the chassis. You can replace the hot-swappable fans
using the procedures in this section when system power is on or off.
CAUTION:
Observe all ESD safety precautions before removing or replacing a fan unit. Failure
to follow ESD safety precautions can result in damage to the server.
NOTE:
A hot-swappable device does not require interaction with the operating system before
the device is removed from or installed into the server.
The dc power to the server does not have to be off to remove or replace a hot-swappable chassis
fan unit.
Removing an Internal Hot-Swappable Chassis Fan Unit
To remove an internal hot-swappable chassis fan unit, follow these steps:
1.
If rack installed, slide the server completely out from the rack. See
.
2.
Remove the top cover. See
“Removing the Top Cover” (page 178)
.
3.
Insert thumb and forefinger into the openings on the top of the fan and squeeze until the fan
releases from the socket.
4.
Pull the fan straight up and out of the chassis.
CAUTION:
To prevent server components from overheating, replace the fan within 20
seconds. Failure to observe this caution results in an automatic server shut down in two
minutes to prevent an overtemperature condition.
